To all whom it may concern..-

Beit known that I, EDWARD T. ROBINSON, a citizen of the United States of America, residing in the city of St. Louis, inthe State of Missouri, have invented certain new and useful Improvemen-ts in Semiconvertible Cars, of which the following is a rull, clear7 and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class'of raill way-cars, more particularly those intended for street-car service, which are so constructed that they may be converted from a condltion for closed `or winter servlce to a condltion i'or open or summer service, and vice versa.

The present improvement lies in certain novel features app'ertaining to the lower window-sashes, which are adapted to be lowered into the usual closed positions or nested together in sets and elevated.

Figure I is an elevation of one of the windows of a car constructed in accordance with my present improvements, the window being seen at theinside thereof. j Fig. II is a vertical cross-section taken through the parts of the car including the window, as. seen in Fig. I. Fig. III is an enlarged horizontal section taken on line III III, "Fig, I. Fig. -IV is a perspective view of one of the sash-pocket strips. Fig. V is an enlarged perspective view of the -antirattler-block utilized on the car-window sashes',

1 designates the deck-'roof of my car, and

. 2 the deck-ceiling, between which is a sashreceiving lvspace 3, into which the windowsashes may be moved when they are out of service, as will hereinafter -more fully appear. 4 designates the window-posts, which are provided with the usual grooves to receive the window-sashes, the inner wall 5 of each groove being curved, as seen in Fig. II. The

lower sash and having an Ainclined face 11, which is adapted to engage one of the catchplates 9 when the lower sash is in closed position, the catch-plate. to be engaged being properly located to provide for the desired engagement at the time that the lower sash is closed, whereby j arring of the sash is obviate'd. v

12 designates the upper sash.

13 are pocket-strips of channel shape, each having one of its llanges secured to the stile of the upper'sash, against the inside face of which the strip is fitted. The channels in these pocket-strips are of proper size to rcceive the lower sash 7 when said sash is elcvated. At the lower end of each pocketstrip 13 is a protuberanee 14, containing a notch 15 and having a beveled face 16. (See Fig. I.) These protuberances are designed to be engaged by the latches 8 of the lower sash when said lower sash is elevated to the full degree in the pocket-strips 13, the bolts of the latches in such instance passing readily into the notches of the protuberances by travcling against the inclined faces. After the two sashes have been nested, together by elevz-ting the lower sash to the upper sash in the manner described both of the sashes are lifted into the space 3 between the deck-roof and deck-ceiling. For the purpose of sustaining the sashes in their raised position within said space I provide angle-brackets 17, which are secured to the side Wall of the car above the wiud. w-openings and within thc space 3, these brackets being so posi- Atianed that the lower sash maybe moved readily into engagclrent therewith and occupy the positini indicated by dattcd lines, Fig. II. Each bracket 17 is provided with a rounded portion 18, against which the upper edge c f the upper sash 12 may strike when the sashes are elevated into the space 3 for the purpose of causing the sashes to be detlected inwardly into the space and away from the bracket-s, so that said brackets will not interfere with the movement of the sashes.

At the rear side of each pocket-strip 13 is entirattler-boss 13 that is adapted to bear against thc curved wall 5 of the window-post groove, (see dotted lines, Fig. IL) in which each upper sash operates and whereby said sash is moved outwardly when lowered into closed position and held from vibration.

19 designates rounded dellecting-blocks mounted on thc shoulders G of thc Window- ICO post grooves land on which the upper sashes rest when in lowered position. These deiecting-blocks have no utility in so far as vthe upper sashes are concerned, but they are utilized to deiect the lower sashes away from the shoulders 6 when the sashes are being lowered from their nested condition in the pocket 3.

I claim- 1. In a semiconvertible car, the combination of grooved window-posts, upper and lower sashes operatable in the grooves in said pests, a pocket-strip carried by the upper sash adapted to receive the lowei` sash, and provided with a notch,I and a catch carried by the lower sash and arranged for engagement in said notch when the lower sash is elevated into said pocket-stripl substantially as set forth.

2. In a semiconvertible car, the combination of grooved window-posts,Y upper and lower sashes operatable in the grooves in said posts, pocket-strips carried by said upper sash adapted to receive said lower sash and l provided with notched protuberances, and catches carried by said lower sash and adapted to enter the notches in said protuberances, substantially as set forth.

3. In a semiconvertible car, the combination of grooved window-posts, upper and lower sashes operatable in the grooves in said posts, pocket-strips carried by said upper sash adapted to receive said lower sash, said pocket-strips being provided with antirattlere bosses adapted to bear against walls of the grooves in said window-posts, substantially as set forth. 'y

4. In a semiconvertible car, the combina,- tion of grooved window-posts, -a catch-plate iXed to one of said posts, a sash operatable in the grooves in said posts, and an antirattlerblock attached to said sash and having an inclined face adapted to engage said catchplate, substantially asset forth.
